25  * Experimental "warm-up" task for core. Executed after IDE startup, it should
26  * pre-initialize some suitable parts of the module to improve first time usage
27  * experience - which might suffer from long response time due to class loading
28  * and various initialization. In java module, the first folder expanding in
29  * explorer or opening java file are things to speed up preferentially.
30  * See org.netbeans.core.WarmUpSupport for details about how the task is run.
